It's not just the voice, they just bore me to death. Band of Horses is the same way for me, just can't get into it. Like I said, I know a lot of people like them, but eh, I'm used to having unpopular opinions.
If you can listen to No One's Gonna Love You and Bloodbuzz Ohio and not be impressed, I... I... I'll be lost and confused
Bloodbuzz is the song that started my dislike of them.
